What do the negative prescription lenses correct?
The correction extends across the viewing lens, rather than forming a separate lower gauge-reading segment. These premade spherical lenses do not reproduce cylinder, axis or prism values from a custom spectacle prescription. Ask your optometrist to confirm whether the available powers are appropriate for each eye.
Select both lens entries carefully, including left/right where the lens model uses different sides. A lens name or colour choice does not determine the correct strength. If your needs fall outside the available options, contact our team about a custom prescription mask.
Apollo Bio Metal lenses require professional fitting with the appropriate tools. Ask us to arrange fitting rather than opening the frame yourself.
How do I check the mask fit before buying?
Face width, shape and nose-pocket comfort matter more than a general age or gender label. Keep hair clear of the skirt and check for an even seal without pressure around the brow or cheeks. Use light strap tension. For a gift, confirm the recipient’s fitting needs before selecting lens powers or fin sizes; our Hallam team can help compare options.
Lens care
Compatible cleaning products
For a coated, prescription or anti-fog-film lens, use only the cleaner or defogger approved by that lens manufacturer. Gear Aid Sea Drops is not recommended for prescription lenses or anti-reflective coatings. For a separate neoprene strap cover, if you use one, we recommend Cressi Neoclean Wetsuit Wash or Revivex Wetsuit Shampoo to clean compatible neoprene. Wash that component separately according to its care label and the cleaner’s dilution instructions, then rinse thoroughly and dry in the shade. These neoprene cleaners are not a recommendation for the mask lens or a regulator assembly.
Rinse with fresh water, dry in the shade and protect the lenses in a case. Use only cleaners and anti-fog treatments suitable for the installed corrective lenses. Avoid abrasive cleaners and flame treatments.
